The air all round us is so dirty. And we breathe dirty air every day. A lot of this air comes from cars. When we a bus or take a walk, we take in the harmful gases that comes out of the cars. If we do sports , we take in even more. These harmful gases do harm to people's health and make people . It can cause people to have a cough or allergies.
It can also make people not live as long. So we must do something. For example, instead of using a car or bus for transportation, we can walk or ride a bicycle because walking and riding a bicycle don't cause much . Also, trees can take harmful gasses from the air and give us more oxygen. So we should plant more trees. If we all do our part, we'll make the air much !
